HEATING AND VENTILATION.
The New Apparatus Placed in the Pom
eroy school House.


eroy school House.
We have noticed briefly the placing of
a new combined heating and ventilating
apparatus in the Pomeroy school house.
on North street. A FREE PRESS represen-
tative has since visited the building and
examined the arrangements in detail.
The apparatus is entirely different from
anything to be found in any public build
ing IN this vicinity. This system of COM
bined heating and ventilation is known as
the Improved Ruttan-Smead Warming
and Nentilating Apparatus" 1t is CON
structed entirely upon scientific princi-
pies, and hence its remarkable and uni
form success Science tells us that when
air Is heated it rises thus the warm par
ticles of air, in room, ascend to the cell
ing while the colder stratum lies near the
floor. The principle upon which the Rut-
tan Smead apparatus works is, that by
conducting off this lower stratum of cold
air-which is also the impure stratum
the warmer air from the furnace fues is
made to diffuse itself evenly throughout
the room. This idea, combined with that
of ventllating tlues constitutes the basal
principle of the Ruttan-Smead system.
1t aims to secure constant and uniform
circulation of air throughout the area to be

systems of heating, by direct radiation, is
That they drive the tOuler and heavier cold

in connection with the heating of build
ing 1t Is secured by eXhausting by
heated shaft the cold foul air and furnish
ing a supply of fresh warmer air. We
shall describe 1t as it has been applied in
the POmeroy school house.
There have been placed in the
basement of this building two large
furnaces, cased with brick, burning wood
or coal, and connected with all the
rooms and corridors of the build
| ing by the usual heating pipes. SO far the
system presents no novel features. But
closer examination reveals the tact that
the heating hues are connected not only
with the furnace, but with two large air
| boxes, each three feet square, opening on
each side of the building. Between the
furnace proper and its brick case the cold,
fresh air, entering bv the outside ducts,
has free circulation, passing around
| every part of the furnace fire box tlueS and
chambers. Converted thus from pure cold
AR into pure warm air, 1t passes INFO the
llueS and Is carried to the different parts of
the building. The warm air enters each
room from register in the wall about four
feet above the floor. This register has no
arrangement for closing whatever but is
| supplied with an ingenlously arranged
] valve, by which the hot air NAV be shut
OF altogether, and pure cold air from the
air boxes supplied IN its stead. or IA modl-
ned current OF warm and cold air MN
Gled. by this arrangement it becomes
impossible to check at any time the vol
ume of fresh air which is pouring into the
room. Either fresh warm air or fresh
cold air is always entering.
But II cur description stopped here we
should have given an idea of hut one half
OF this admirable system. Let US now see
how the continuous ventilation" which
Is its principal feature is secured In each
room there are from one to tour registers
and tiues in the floor, connected with a
large ventilatlug stack, for the purpose of
carrying off the cold and foul air which,
| being heavier, collects along the floor.
Thus complete system of ventilation,
with continuous current OF pure air, is
secured. Before the foul air is carried
into the veutilating stack, ii is passed
| through the dry closets in the basement.
| Ihey do away altogether with the use OF
water and sewer connections, and form
one of the most desirable feat lures OF the
system. Every Objectionable feature of
the sewer system is avoided by these clean
| ly and healthful closets and urlnals.
TO show what this system OF heating
can do, we will state that II was tried Tor
the first time in the PomerOy school house
on the morning of Jan. 3. The building af-
ter the intense cold of Sunday night, when
! the clercury fell from 10 10 20 below zero
was thoroughly chilled About two hours
after the tires were started in the morn
ing the thermometers registered 20 de
| gyees in all parts of the building and all
| the rooms were uniformly heated AT the
| close of each school session, without the
opening of a window or any other direct
avenue To the outer air, the air in every
room was found to he as fresh and pure as
in the morning. The incalCulabe advan-
tage arising from this feature OF the sys-
TEN, in school houses, where both the
health and the mental grasp of the pupils
depend SO much on pure air, may readily
| be seen,
The apparatus has now been thorough
tested for two weeks, and notwlthstand-
ing the extreme cold weather during that
time, the entire building has been easily
heated To the temperature desired, with
pure air, 1t may be added that the school
